SBI 满装圆柱滚子轴承 Full Complement Cylindrical Roller Bearings 洛阳世必爱特种轴承有限公司 Luoyang SBI Special Bearing Co., Ltd.

满装圆柱滚子轴承 满装圆柱滚子轴承是为了承受重载荷而设计的。在同样宽度下这种轴承与传统型 带保持架轴承相比具有极高的承载能力径向截面小可以节省空间但转速相对较 低。所有多列圆柱滚子轴承在外圈上有一润滑槽和润滑孔。 为了使轴承正常工作在连续运转的情况下轴承必须承受一定的最小负荷即 C/P<25。否则因润滑不足和高速运转时会加剧磨损。 NCF··V 型满装圆柱滚子轴承外圈具单挡边无挡边侧有锁圈可对机轴作单向定 · 位轴承内部的轴向间隙“S”保证了机轴相对于轴承箱的轴向定位移。 “S”值可向本公 司询问。 NJ··V 型满装圆柱滚子轴承用于极重负荷和低速场合具有自锁滚子组即使拆下 · 内圈滚子也不会散落因此该型轴承安装拆卸方便可承受单向轴向负荷作单向定 位。 NNF··2LSNVY 型双列满装圆柱滚子轴承具有两个内圈两个内圈由夹持圈联接在 · 一起不可分离外圈有一个中挡边可承受双向的轴向负荷用作定位轴承。由于两 列滚子之间的距离较大还可承受倾覆力矩。外圈表面有两个止动槽可以轴向定位。 该型轴承两侧装有接触式密封圈内装锂基脂运行温度限于40℃80℃。在一定 的条件下该型轴承无需保养但当运行时有水汽或污染且常为中速或高速运行则 必须补充润滑。在采用机油润滑的场合需拆除密封圈且清洗轴承内的润滑脂采用 机油润滑时转中提高 30。 满装圆柱滚子轴承的尺寸公差和几何偏差应符合 GB/T307.1-94(ISO492-...

轴承座公差的选择原则 工作条件 机床主轴、 高精度装置 所有轴承直径 一般应用 内圈受旋转负荷 或变动负荷 正常负荷 注表列轴承座孔公差仅适用于钢或铸铁轴承座。轴公差仅适用于实心轴。如果用轻金属轴承座时应选择较紧的配合。由 于各种因素的影响 不可能找到一条包括各种因素的、 正确的配合公差选择原则。 因此 表中所列之值仅只能当作是参考值。

Full complement cylindrical roller bearings SBI full complement cylindrical roller bearings are designed to carry heavy load. Comparing with traditional bearings with cage, full complement cylindrical bearings have much higher loading capacity. The radial cross section of the type of bearings is very small. So it can be very space-saving. However the limiting speed of the bearings is relatively lower. All the multi-row cylindrical roller bearings are with a lubrication groove and one nipple on the outer ring. A minimal load is required (C/P<25) for the bearings to run well in succession. Otherwise...

bearings and stationary bearings, the rib that carrying axial load must be fully supported. Attention: when mounting and dismantling the cylindrical roller bearings, the force should not be transmitted directly through the cylindrical rollers and the rib of rings.
